1 Claim.

This invention is a method and means for securing roofing tile to a roof structure.

The main object of the invention is to provide an inexpensive method and means for securing roofing tile and which may be accomplished by the layman.

Another object of the invention is to provide a method of securing tile roofing in which the ordinary sheathing of the roof structure may be replaced by narrow purlins, thereby cutting the sheathing cost to about twenty percent of normal as less than one-fifth the usual amount of lumber is required.

A further object of the invention is to provide roofing tile with means whereby the tile may be tied to the roof structure by flexible elements.

Other objects and advantages of the invention will become apparent as the following description is read on the drawing forming a part of this specification and in which similar reference characters are used to designate similar parts throughout the several views and in which:

Fig. 1 is a section through a roof structure showing my method applied thereto.

Fig. 2 is a bottom view of a roofing tile, showing my invention applied thereto.

Fig. 3 is a section taken on line 33 of Fig. 2, and

Fig. 4. is a plan view of a group of laid tile indicating more clearly the method of securing the tile.

The invention consists primarily in tying the tile, by means of flexible elements to purlins and is indicated in the preferred form at 10, Figs.

1 and 4 in which case, the tile are sewed in place as will be further explained.

Referring to the drawing, it will be observed that each tile 11 is provided with ears 12 and 13 which are formed integrally with the tile and project from the undersurface thereof, and positioned intermediate the center and each end of the tile, and each of which is provided with an aperture 14.

The preferred method of securing the tile is to provide a supporting structure of the usual trusses or rafters 15, with purlins l6 spaced apart a distance equal to the length of the tile, the purlins when made of wood being substantially two inches in width, and of a height suitable to carry the load.

The tile 11 are then laid in tiers, the tiles of adjacent tiers being staggered, with their adjacent ends overlapped and with the edges of adjacent tiles in each tier overlapped, as indicated in Figs. 1 and 4, after which a wire, cable or other flexible element is tied at one end to the roof structure, as indicated at 23, then passed successively through adjacent ears of upper and lower tiers of tile in zigzag relation, indicated in Fig. 4 by passing through an car 13 at 17, then through an ear 12 at 18, car 13 at 19, ear 12 at 20, the wire or cable in passing between cars 12 and 13 passing under the purlin as shown at 21, substantially stitching the tile to the roof structure.

The upper portions of the tiles of the topmost roll, and the lower ends of the tiles of the lowermost tiles may have their ends anchored to the roof structure in any desired manner. For purposes of illustration, ties 22 are shown at the upper portion of Figure 1, the same being engaged with a purlin l6 and an adjacent lug 12 of the tile. Inasmuch as the lowermost tiles may be secured in identically the same manner, illustration thereof is considered unnecessary.

By reference to Figure 1 of the drawing, it will be readily seen that applicants method in securing tile to a roof results in a tension being placed longitudinally of the tile thereby forcing their interlocking ends securely together under tension, while simultaneously tensioning the overlapping ends of the tile downwardly against the upper face of the purlins 16 and maintaining this tension when the ends of the flexible element 10 are secured to the opposite sides of the roof structure.

Having described an operable method of applying the invention it will be understood the variations in construction and arrangement of parts which are consistent with the appended claims may be resorted to without detracting from the spirit or scope of the invention or sacrificing any of the advantages thereof.

We claim:

In a roof structure, the combination with relatively spaced rafters, and relatively spaced transversely disposed purlins secured to said rafters, of a plurality of tiers of tiles, the tiles of adjacent tiers being relatively staggered with their adjacent ends in overlapped relation, and the tiles of each tier having their adjacent edges in overlapped relation, each tile having its underside provided with a pair of depending, longitudinally spaced integral ears, so relatively positioned that the overlapped ends of the tiles of adjacent tiers are respectively provided with depending ears located adjacent to and on opposite sides of a purlin, and a flexible tie member having its ends secured to said purlin and its intermediate portion alternately engaged with those cars which are on opposite sides of said purlin and passed beneath the purlin at positions between the last mentioned ears and in such manner that the tiles adjacent said purlin are drawn together by a pulling tension applied to all of them.
